Question: Does Windows7 32-bit support more than 4G of RAM? XP and Vista 32-bit versions wouldn't see more than 3.5Gb (or 4Gb if you did some tweaking...at your own risk), you'd have to go to the 64-bit OS to get up above 4Gb.
Nope. You'll need the 64 bit version for that. Actually the kernel is virtually the same as Viasta's and XP's kernel, with the same limitations. You can have more RAM then 3.5, but it'll be used like some sort of extended memory, like the memory in the old days of MS-DOS.
